correct answer is maturation zone - elongation zone - cell division zone

Answer 2

Regions of root from base to root tip are the Maturation zone - Elongation zone - Cell division zone.

Option (B).

Explanation:

Maturation zone:

• The base of the root is defined as the maturation zone which contains the vascular cylinder and root hair.

• In this region, completely functional cells were found.

• The elongated cells complete their differentiation into the tissues of the first body in this zone.

Zone of cell elongation:

• In this zone, the cellular expansion is responsible for accelerating root cap and apical tip forward through the soil.

Zone of cell division:

• This zone contains apical meristem cells which give contribute to the primary body of the plant.
